Fix dialog unmounting and unpin @chakra-ui/react (#67647)

[prattik-wav]

capped @chakra-ui/react at ~3.34.0 due to a page-unresponsive bug triggered by @ark-ui/react >= 5.36. The bug occurred because dialogs were conditionally unmounted before the close transition could run, leaving a pointer-events: none lock permanently stuck on the document.

This commit resolves the underlying mounting issue and restores the upgrade path by:

• Replacing conditionally-mounted dialogs with always-rendered components in Clear and Mark-as actions, relying on lazyMount so close transitions execute cleanly.
• Gating expensive dry-run queries inside the dialogs with enabled: open to prevent unnecessary network requests.
• Wrapping the onClose handler to properly reset local form state (e.g., typed notes and selected options) when a dialog is dismissed.
• Unpinning and bumping @chakra-ui/react to ^3.35.0 in the UI package.
• Removing the related dependency caveats from CONTRIBUTING.md.

Resolves: #67647
